This patch series adds support for preservation of the VM generation ID buffer address in xenstore across save/restore and migrate, and also code to increment the value in all cases except for migration. Patch 1 modifies the guest ro and rw node creation to an open coding style and cleans up some extraneous node creation. Patch 2 modifies creation of the hvmloader key in xenstore and adds

The following series of 10 patches is a merge of the xenfb and xenconsoled functionality into the qemu-dm code. The general approach taken is to have qemu-dm provide two machine types - one for xen paravirt, the other for fullyvirt. For compatability the later is the default. The goals overall are to kill LibVNCServer, remove alot of code duplication and/or parallel impls of the same concepts, and

Hey Ian and Stefano, Please see this thread: http://lists.xen.org/archives/html/xen-devel/2013-05/msg01053.html for the debug patches and some of the discussion. These three patches fix an race that has been in QEMU traditional for a long time. The guts of the bug is that if you have a guest with these options: vcpus=1 maxvcpus=32 and do ''xl vcpu-set <guest> 32'' the

Hello I'm trying to use C random generator function drand48() which return floating-point values, uniformly distributed over [0,1], (http://www.opengroup.org/onlinepubs/007908799/xsh/drand48.html). When values are returned to R, they are not in [0,1]. A simple C program using drand48() gives values in [0,1] so I suppose there is a problem (type definition ?) between C and R. Here are R and C function and an example. # R function simulC <- function(n) { dyn.load("...

It is noted that the above statements were made notwithstanding the ERRORS section of pow() in POSIX.1-2017 XSH Chapter 3, which specifies a domain error except perhaps by deference to the C standard due to a conflict between the POSIX and the C wording. The transformation in question causes EDOM for pow(-Inf, 0.5) even on platforms where the system library implementation of pow does not cause this situati...
